MOTOR SUPPORT Filed Nov. 4, 1929 Patented Apr. 28, 1931 UNED STATESPATENT OFFICE FINN T. IRGENS OF MILWAUKEE, WISCONSIN, ASSIGNOR TOOUTBOARD MOTORS COR- PORATION, OF MILWAUKEE, WISCONSIN, A CORPORATION OFMICHIGAN MOTOR SUPPORT Application filed November 4, 1929. Serial No.404,570.

This invention relates to improvements in motor supports. i

It is the object of the invention to provide a novel and improved meansfor carry- 5 ing an outboard motor in a recumbent position (when not inuse) without injury to its fuel tank.

When outboard motors are laid down for any purpose, as fortransportation, or as an incident to manipulation in positioning orremoving the motors. from the boat, the motors are ordinarily laid uponthe ground with the tiller handle uppermost. The design of outboardmotors has heretofore been such that in the position aforesaid, the fueltank of the motor has contacted with the ground and has been subject todents, scratches, and cuts which mar its appearance and tend to loosenthe tank from its support and to cause it to leak To overcome theseobjections I have provided extended cooling fins on the muffler headswhich perform the function of feet and project from the mufiler beyond aplane including the surface ofthe fuel tank and the point of support atthe lower unit of the motor.

In the drawings:

Figure l is a side elevation of a motor. supported in accordance withthis invention.

Figure 2 is a detail in perspective of the mufiier shown in Figure 1 andexemplifying one way in which suitable supporting feet may beeconomically and inconspicuously formed on theimotor.

Like parts are identified by the same reference characters in bothviews.

The outboard motor comprises a supporting bracket 5, bearing sleeve 6,tubular support 7, engine 8 and lower unit 9. p The engine is providedwith the usual fuel tank 10 and fly wheel magneto 11. The engine crankshaft is not illustrated but it will be understood to be extendedthrough the tubular support 7 in the usual way and connected to drivethe propeller 12.

When the motor is in a recumbent position, as illustrated in Figure 1,its lower unit is usually supported by the propeller 12 or the propellernut 13. In accordance with this invention the engine is provided with ameans of support other than fuel tank 10 for keeping the upper end ofthe motor sufficiently remote fromthe ground so that the fuel tank willnot contact therewith.

For this purpose, I provide the usual heads 14 and 15 of the mufiier 16with feet inder castings of the engine in accordance with usualpractice, it will be obvious that the muflier itself, which is usuallymade of sheet metal, is relieved of load in addition to the reliefafforded to the fuel tank. The muffler, however, is entirely adequate tobrace the heads against displacement under any load to which they aresubjected in performance of their new function of supporting the motor.

I claim: I

1. In an-outboard motor, the combination with an engine having a fueltank so positioned as to lie therebeneath in the recumbent position ofthe motor, of a m'ufller for 'said engine provided with vents in itsintermediate portions and supports for said engine adjacent the ends ofthe muflier and projecting beyond said tank and intermediate portions ofthe muflie'r, whereby to be adapted in the recumbent position of themotor to hold said tank and vented mufiler portions off the ground.

2. In an outboard motor, the combination 4 with an engine and a lowerunit connected therewith and provided with means adapted to rest on theground in the recumbent position of the motor, (if a fuel tank for saidengine positioned to lie therebeneath in said motor position, a mufflerlikewise located to lie beneath said engine in the recumbent position ofthe motor, and members at the ends of the muffler connected with saidengine and provided with supports extending beyond the muffler and fueltank, whereby to carry the weight of the engine and to relieve the tankand mufiler thereof.

3. In an outboard motor, the combination with an engine and a lower unitconnected therewith and provided with means adapted to rest on theground in the recumbent position of the motor, of a fuel tank for saidengine positioned to lie therebeneath in said motor position, a mufilerlikewise located to lie beneath said engine in the recumbent position ofthe motor, and members at the ends of the mufller connected with saidengine and provided with supports extending beyond the mufiier and fueltank, whereby to carry the weight of the en e and to relieve the tankand mufiier t ereof, said members comprising exhaust manifolds for saidengine.

, 4. In an outboard motor, the combination with an engine and a lowerunit connected therewith and provided with means adapted to rest on theground in the recumbent position of the motor, of a fuel tank for saidengine positioned to lie therebeneath in said motor position, a muflierlikewise located to lie beneath said engine in the recumbent position ofthe motor and members at the ends of the muflier connected with saidengine and provided with supports extending beyond the mufiler andfueltank, whereby to carry the weight of the engine and to reheve the tankand muflier thereof said members comprising exhaust manifolds forv saidengine having cooling flanges extended to provide said supports.

5. In an outboard motor having-cylinders at opposite sides of a centralaxis, the combination with said cylinders, of engine supports connectedtherewith substantially at the ends of said cylinders and pro'ectingrearwardl at widely spaced points whereby to carry t e weight of thecylinders directly and provide sta le engine support in a recumbentmotor position, and exhaust gas mufiler means having lessrearward extentthan said supports, whereby to be protected by said supports in saidmotor position.

6. In an outboard motor having engine cylinders with these ends widelyspaced laterally,-the combination with said-cylinders,

. of exhaust manifold castings connected with the cylinders near theirends and provided with rearwardly extendin feet for the directsupport ofsaid cylinders in recumbent motor ositions, and exhaust means lessremote om said cylinders than said feet, whereby to be protected inrecumbent motor positions.
